Mark 14:66-68

66 And while Peter was down in the open square of the building, one of the servant-girls of the high priest came;

67 And seeing Peter warming himself by the fire, she gave him a look, and said, You were with this Nazarene, even Jesus.

68 But he said, I have no knowledge of him, or of what you are saying: and he went out into the doorway; and there came the cry of a cock.
